Green Keys not saving to/loading from save file correctly on Linux/macOS

[GammaTendonNine]

Results of My Testing on macOS

1. The key do in fact save to the text save file correctly, immediately upon collection, including the specific level that it came from (e.g. keys = "1101000000" after collecting BOB, WF, & CCM keys).
2. While the number of collected keys does appear to get loaded from the save file when relaunching the game (according to the source code), all keys reappear in game, and upon collection it overwrites the entire keys = string in the save file (e.g. keys = "1000000000" after relaunching the game and collecting the BOB key).

So as you said, when you reload the game you have to collect them all (again) and then unlock Luigi in a single run. If you unlock Luigi however, this will be saved and you will be Luigi when you reload the game, but will not be able to switch back to Mario via the Boo Hat until you've recollected all keys (or edit the save file manually).

I always assumed this was by design to facilitate the speedrun competitions that are put on in Discord, and the keys are saved to the save file to track the total to determine when to unlock Luigi/Mario during a single run. Let me confirm with @DorfDork and I can look into fixing the Luigi Key Loading/Saving functionality if that is the intended behavior.

@WandeingLagomorph793 It appears this issue is isolated to Linux/macOS, it is not the intended behavior, and I'm working on tracking down the root cause.
